Some anesthesiologists are pain specialists who may see patients in a clinic. Pain medicine doctors are experts at diagnosing why you are having pain as well as treating the pain itself. Some of the more common pain problems they manage include: arthritis, back and neck pain, cancer pain, nerve pain, migraine headaches, shingles, phantom limb pain for amputees and pain caused by AIDS. They also manage acute pain caused by surgery, a debilitating illness or a serious injury.
Acute pain begins suddenly and is usually sharp in quality. It serves as a warning of disease or a threat to the body. Acute pain might be caused by many events or circumstances, including:
Acute pain might be mild and last just a moment, or it might be severe and last for weeks or months. In most cases, acute pain does not last longer than six months, and it disappears when the underlying cause of pain has been treated or has healed. Unrelieved acute pain, however, might lead to chronic pain.
Chronic pain persists despite the fact that the injury has healed. Pain signals remain active in the nervous system for weeks, months, or years. Physical effects include tense muscles, limited mobility, a lack of energy, and changes in appetite. Emotional effects include depression, anger, anxiety, and fear of re-injury. Such a fear might hinder a person's ability to return to normal work or leisure activities. Common chronic pain complaints include:
Chronic pain might have originated with an initial trauma/injury or infection, or there might be an ongoing cause of pain. However, some people suffer chronic pain in the absence of any past injury or evidence of body damage.
Injection Treatments
Local anesthetics (such as Novocain®), with or without cortisone-like medicines, can be injected around nerve roots and into muscles or joints. These medicines reduce swelling, irritation, muscle spasms and abnormal nerve activity that can cause pain.
Nerve blocks
Often a group of nerves, called a plexus or ganglion, that causes pain to a specific organ or body region can be blocked with local anesthetics. If successful, another solution that numbs the nerves can then be injected.
